Overview

2012 PH6 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2012 PH6 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2012 PH6 orbits the sun every 849 days (2.32 years), coming as close as 1.14 AU and reaching as far as 2.37 AU from the sun. Based on its brightness and the way it reflects light, 2012 PH6 is probably between 0.160 to 0.358 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2012 PH6's orbit is 0.16 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2012 PH6 has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Aug. 13, 2019 27,572,272 13.352
Aug. 16, 2084 26,737,234 12.258
Aug. 13, 2091 29,263,943 13.590
Aug. 16, 2156 25,373,440 12.328

Images and Observations

2012 PH6's orbit is determined by observations dating back to Aug. 10, 2012. It was last officially observed on Aug. 4, 2019. The IAU Minor Planet Center records 91 observations used to determine its orbit.
